My Tesla Powerwall Is Here! 7.5 KWh Power Curve Explanation Tech Info DIY http://www.youtube.com/watch?v=uC12qdkExTE First thing you should do is solar power your hot water heater because it is the #2 thing in the house that pulls BIG power and you can do it more direct WITHOUT INVERTERS OR BATTERIES see http://techluck.com Your water heater is like a 6 KWh heat battery that you pay to charge every day! And it's already installed! Why not put it on solar the easy way? With the Li-Ion batteries there's no more battery acid checking or fumes and takes up less space. They can be partly charged with no problems. To get an idea of the size of these, it's about 3 car batteries in that same space of the 3 stacks. My "wall" has more configuring to be done with things that give me power in the daytime. The batteries are just for night and are just one system. So stay tuned! (please subscribe) Note that a actual Tesla Powerwall is just the battery and is high voltage of around 350V. You need to add a special inverter which is generally 2000W with other features like grid switch over which you can DIY if you have some electrical skills. My system is 24V and uses a standard pure sine wave inverter and 24V charge controllers (modified, see below). If you are worried about a BMS and balancing the batteries, remember they are mostly in parallel, not a big string all in series. I have been monitoring them and so far they are OK. I can easily bottom balance them if needed. See how they are connected in the video. The Ford Fusion hybrid battery looks promising for easy DIY, it has easy to use screw terminals also.
